COMBINED WRENCH ANDGRIPPING DEVICE.

SPECIFICATION forming part of Letters Patent No. 674,680, dated May 21, 1901.

, Application filed August 10,1900. Serial No. 26,451. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH T. GODBOUT, a citizen of the United States of America, and a resident of the city and county of Worcester, State of Massachusetts, have invented certain new and useful Improvements in a Combined Wrench and Gripping Device, of which the following is a specification.

My invention relates to combined wrenches ro and gripping devices, its chief object being to provide a wrench with a powerful jaw action, with several jaws adapted for various uses, and with such further improvements as are hereinafter set forth.

In the common monkey-wrench the nut or bolt for adjusting the jaws is usually a small one located at one side of the jaw and adapted to be operated by the thumb and finger. The grip obtained between the jaws by this means zo is very imperfect and oftentimes inadequate for many kinds of work which it is desirable to do with such a tool. Furthermore, but one set of jaws is usually provided and these are not adapted for a large range or for various z5 kinds of work. In my invention I provide a pair on each side of the wrench, as well as a pair of small jaws or cutting-dogs in the top of the wrench. These several pairs of jaws are operated by turning the entire handle,

3o which is adapted to be grasped firmly in the whole hand. Thus a very powerful grip can be obtained between the jaws of the several pairs.

My invention consists in the construction 3 5 hereinafter described and in the combination of parts set forth in the claims.

Figure 1 is a side elevation of my wrench.

Fig. 2 is an elevation taken at right angles to Fig. 1 in the direction of the arrow 2. Fig. 4o 3 is a sectional view; and Fig. 4 is a View of a-portion of the wrench, showing removable jaw-faces for dierent kinds of work.

The rectangular body of the wrench is provided with the fixed jaws l1 12, extending from opposite sides thereof. Fitted to slide on the rectangular body 10 is the slidable member 13, having the laterally-extending jaws 14 15 to act with the jaws 11 12, respectively. Integral with and extending down- 5o ward from the rectangular body is the threaded shank 16, on which the handle 17 is threaded, which fits and screws onto said shank.

The slidablemember 13 is provided with a conical concave bearing 1S, adapted to fit a similar conical convex bearing on the handle, so that by turning the handle the movable jaws are advanced toward the fixed jaws.

The entire body portion 10 and" shank 16 is cored or drilled out to receive the rod 19. The slidable jaws are attached to this rod by means of the screw 20, which may extend through said rod and be fastened into both sides`of the slidable member. The body 10 is provided'with slots, as 21, in which the screw 20 slides to permit said jaws to be operated back and forth thereon.

Ou the rod 19 and within the body 10 is mounted the spiral spring 22. This spring acts against the rod to normally force it downward by means of the screw 23. The upper end of the spring acts against the body portion by means of the screws 24 24', or, if preferred, by a shoulder formed in the body portion and performing the same function as a screw. By means of this spring the fixed and movable jaws are normally held apart. The lower end of the rod may be extended, as at 25, and provided with the shoulder 26 for the screw 27 in the handle to engage to prevent the handle being entirely unscrewed from the shank 16. The lower end of the rod may engage the bottom of the screwthreaded hole in the handle or to provide for adjustment may engage the screw-plug 28, threaded in the end of the handle, so that the rod may receive a direct powerful upward thrust when the handle is screwed on.

The housing 39 is provided in an extension of the body portion 10 above the jaws 11 12. Journaled in this housing on the screws or rivets 30 3l are steel jaws or dogs 32 33. The lower ends of these jaws are normally forced together by springs 34 35, resting at the bottom of the housing, and thus the upper ends of the jaws are opened. Mounted on the upper end of the rod 19 and bearing against the inner sides of the lower end of the jaws is the wedge-shaped plug 36. Thus the fixed and movable jaws, already described, are forced together by turning the handle and ad vancing the rod and wedge-shaped plug between the lower ends of the jaws. These upper jaws are thus forced together by a very powerful wedge-'and-lever motion, as described,

IOO

by which a very strong grip can be obtained between the small jaws, and, if desired, these jaws can be made with cutting edges for the purpose of cutting wire, nails, &c.

This wrench is adapted for a pipe-wrench or for a pipe-cutter, and for such purposes I provide removable jaws, as shown in Fig. 4. The jaws 37 38 are adapted to it into and be held to the face of the jaws 11 la in any suitable way and are provided with the usual gripping-teeth 40, as shown. Another form of removable jaws 4l is shown attached to the removable faces of the jaws l2 15.

The operation of my invention should be clear from the above description, the fixed and movable jaws being held firmly apart by means of the spiral spring acting between the body portion of the fixed jaws and the rod which is attached to the body portion of the movable jaws, and the respective jaws are closed and a most powerful grip between them obtained by turning the handle, which is knnrled on the outside and can be gripped iirmly in the hand and which has its bearings between the threaded shank of the iixed jaws and the conical bearing of the movable jaws. The small gripping-jaws in th top of the wrench are operated by the same means, the rod being forced upward by the handle and the wedge entering between the lower ends of these jaws, which forces them together. These jaws may be used for pulling out screws or nails, for cutting wire, or for any other use in which a powerful grip is desired.

Changes may be made in the form and construction of my wrench without departing from the spirit of my invention, and I do not confine myself to the particular details shown; but

What I claim, and desire to secure by Letters Patent, is-

l. In a wrench or the like, a fixed jaw, a movable jaw, movable gripping members carried by the body portion of the wrench, means for operating said jaws, and connection between said movable jaw and said gripping members for operating the latter by the movement of the former; substantially as described. Y

2. In a wrench or the like, a fixed jaw, a

movable jaw, gripping members carried by the body portion of the wrench, means for operating said jaws, a rod engaging said gripping members to operate them by its movement, and connection between said rod and said movable jaw whereby said parts move together; substantially as described.

3. In a wrench or the like, a fixed jaw, a movable jaw, movable gripping members -mounted .upon said fixed jaw, means for operating said jaws, and connection between said gripping members and said movable jaw for operating the former by the movement of the latter; substantially as described.

4. In a wrench or the like, a Xed jaw havinga body portion provided with a slot, a movable jaw operating along the slotted portion of the fixed jaw, movable gripping members mounted upon said fixed jaw, a rod Within an opening in said fixed jaw and operatively engaging said gripping members, a pin connecting said rod and said movable jaw and extending through said slot in said fixed jaw, and means for operating said movable jaw; substantially as described.

5. In a wrench or the like, a fixed jaw, a movable jaw, movable gripping members mounted upon the body portion of the wrench, a rod operativelyengaging said gripping members, connection between said rod and said movable jaw whereby said parts move together, and means for yieldingly holding said fixed and movable jaws apart whereby said rod'is moved into position to permit opening of said gripping members; substantially as described.

6. In a wrench or the like, a fixed jaw having an opening therein, a movable jaw, movable gripping members mounted upon the body portion of the wrench, a rod operative in said opening in said fixed jaw and operatively engaging said gripping members, connection between said rod and movable jaw whereby said parts move together, and a spring engaging said rod and said iixed jaw and tending to force said jaws apart and to move said rod intoposition to permit opening of said gripping members; substantially as described.

'7. The combination with the body portion and xed jaws, of the slidable jaws mounted to slide on said body portion, the rod adapted to slide within the body portion, engaging the slidable jaws and having a wedge-shaped'end thereon, a spiral spring mounted on said rod and acting between said rod and the body portion, the gripping or cutting dogs mounted in the body portion, and engaging the wedgeshaped end of said rod, and a screw-threaded handle acting between said fixed jaws and movable jaws and adapted to close the same and to force said rod and wedge-shaped end into engagement with said gripping or cutting dogs to close the latter, substantially as described.
